GULTIVATOR ATTACHMENT Itefiled for abandoned application Serial No.266*,252, filed. March 31, 1928.

This application filed December 30, 1929. Serial No. 417,575.

This application is filed in the place and stead of my abandonedapplication Serial No. 266,252.

The present invention relates to an attachment for cultivators and hasfor its prime object to provide a. structure which will lift bean or peavines from the ground and lead them to a cutter.

Another very important object of the in vention resides in the provisionof a unit comprising a shovel and a knife disposed rearwardly of theshovel and means for leading vines lifted by the shovel to the cutter.

A still further very important object of the invention resides in theprovision of a cultivator attachment of this nature which is simple inits construction, inexpensive to manufacture, strong and durable,thoroughly efficient and reliable in use, and otherwise well adapted tothe purpose. for which it is designed.

with the above and numerous other objects in view, as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawings Figure 1 is a top plan view of a plurality of theattachments on the cross beams of a cultivator.

Figure 2 is a vertical section through the cross beam showing one of theattachments in side elevation.

Figure 3 is a front elevation of several of the attachments on the crossbeams.

Figure 4 is a detail section, taken substantially on the line 4-4 ofFigure 2.

Figure 5 is a perspective view of one of the cutters.

Figure 6 is a perspective view of one of the guides.

Referring to the drawings in detail, it will be seen that numerals 5 and6 denote respectively the front and rear cross beams of a cultivator. Aplurality of my attachments are fixed to the cross beams and as theseattachments are identical in construction, only one unit will bedescribed in detail.

Referring to one of the units in detail, it will be seen that thenumeral 7 denotes a shank having a horizontal portion fixed under thefront beam 5 by means of U-bolts 8 and plates 9, and extending forwardlyand rearwardly of the beam 5. The forward end of the shank 7 is curveddownwardly and a shank 10 of a shovel 11 is adjustably attached to thelower end thereof by pin and slot connections 12 so as to provide foradjustment. A shank 14 is attached to the beam 6 extending forwardly andrearwardly therefrom, and has an intermediate portion of its front partpivoted as at 15 to the rear end of the shank 7.

The end of the front bar of the shank portion is provided with anarcuate slot 16 concentric with respect to the pivot 15 and re ceiving apin 17 projecting laterally from an intermediate portion of the rearpart of the shank 7', thereby allowing adjustment between the shanks 7and 14. The rear part of the shank 14L curves downwardly and forwardlyand on the bottom end thereof there is disposed a knife 18, diagonallydisposed with respect to the path of the unit, as is clearly indicatedin Figure 1. A guide, in the form of a U-shaped elongated rod 19 has itsbight disposed about a bolt 20 and secured thereto by means of a nut 21,or in any other desired manner, so as to extend rearwardly over therearward portion of the knife 18.

From the above detailed description of the construction, it will be seenthat the attachment may be used on most any two or four row cultivator,and operates with a relatively light draft. The shovels lift the vinesout of the ground and the guide rod leads them to the knife, where theywill be out.

It is thought that the construction, utility and advantages of thisinvention will now be It will be apparent that changes in the details ofconstruction, and in the combination and arrangement of parts may beresorted to, without departing from the spirit or scope of the inventionas hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is 1. A unit ofthe class described comprising a pair of shanks, means attaching theshanks together, means for attaching the shanks to beams, one shankextending forwardly and curved downwardly, a shovel fixed to the end ofsaid one shank, the other shank being curved downwardly and rearwardlyand then forwardly, a knife attached to the end of the other shankdiagonally to the path of movement of the unit, a guide extending fromthe shovel rearwardly over the rear portion of the knife.

2. A unit of the class described comprising a pair of shanks, meansadjustably connecting the rear end of one shank with the forward end ofthe other shank for attaching the shanks to cultivator beams, theforward end of said one shank being curved downwardly and forwardly, a.shovel attached to the lower end of said one shank, said other shankbeing curved downwardly, rearwardly and then forwardly, a knife attachedto the end of said other shank diagonally to the path of movement of theunit, and a U-shaped guide rod extending between the ends of the shanks.

3. A unit of the class described comprising a pair of shanks, meansadjustably connecting the rear end of one shank with the forward end ofthe other shank for attaching the shank to cultivator beams, the forwardend of said one shank being curved clownwardly and forwardly, a shovelattached to the lower end of said one shank, said other shank beingcurved downwardly, rearwardly and then forwardly, a knife attached tothe end of said other shank diagonally to the path of movement of theunit, a U-shaped guide rod extending between the ends of the shanks, abolt on the shovel, the b ight of the guide rod extending about thebolt, and means on the bolt for holding the bight of the guide rodthereon.

In testimony whereof I afiix my signature.

WILLIAM D. EDWARDS.
